Quickstart

This page gives a brief introduction to the library. It assumes you have the library installed. If you don’t, check the Installing portion.

A Minimal Bot

Let’s make a bot that responds to a specific message and walk you through it.

It looks something like this:

Note

Because this example utilizes message content, it requires the Intents.message_content privileged intent.

import discord

intents = discord.Intents.default()
intents.message_content = True

client = discord.Client(intents=intents)

@client.event
async def on_ready():
    print(f'We have logged in as {client.user}')

@client.event
async def on_message(message):
    if message.author == client.user:
        return

    if message.content.startswith('$hello'):
        await message.channel.send('Hello!')

client.run('your token here')

Let’s name this file example_bot.py. Make sure not to name it discord.py as that’ll conflict with the library.

There’s a lot going on here, so let’s walk you through it step by step:

  1. The first line just imports the library, if this raises a ModuleNotFoundError or ImportError then head on over to Installing section to properly install.

  2. Next, we create an instance of a Client. This client is our connection to Discord.

  3. We then use the Client.event() decorator to register an event. This library has many events. Since this library is asynchronous, we do things in a “callback” style manner.

    A callback is essentially a function that is called when something happens. In our case, the on_ready() event is called when the bot has finished logging in and setting things up and the on_message() event is called when the bot has received a message.

  4. Since the on_message() event triggers for every message received, we have to make sure that we ignore messages from ourselves. We do this by checking if the Message.author is the same as the Client.user.

  5. Afterwards, we check if the Message.content starts with '$hello'. If it does, then we send a message in the channel it was used in with 'Hello!'. This is a basic way of handling commands, which can be later automated with the discord.ext.commands – Bot commands framework framework.

  6. Finally, we run the bot with our login token. If you need help getting your token or creating a bot, look in the Creating a Bot Account section.

Now that we’ve made a bot, we have to run the bot. Luckily, this is simple since this is just a Python script, we can run it directly.

On Windows:

$ py -3 example_bot.py

On other systems:

$ python3 example_bot.py

Now you can try playing around with your basic bot.

A Minimal Bot with Slash Commands

As a continuation, let’s create a bot that registers a simple slash command!

It looks something like this:

import discord

bot = discord.Bot()

@bot.event
async def on_ready():
    print(f"We have logged in as {bot.user}")

@bot.slash_command(guild_ids=[your, guild_ids, here])
async def hello(ctx):
    await ctx.respond("Hello!")

bot.run("your token here")

Let’s look at the differences compared to the previous example, step-by-step:

  1. The first line remains unchanged.

  2. Next, we create an instance of Bot. This is different from Client, as it supports slash command creation and other features, while inheriting all the features of Client.

  3. We then use the Bot.slash_command() decorator to register a new slash command. The guild_ids attribute contains a list of guilds where this command will be active. If you omit it, the command will be globally available, and may take up to an hour to register.

  4. Afterwards, we trigger a response to the slash command in the form of a text reply. Please note that all slash commands must have some form of response, otherwise they will fail.

  5. Finally, we, once again, run the bot with our login token.

Congratulations! Now you have created your first slash command!
